Appendix A: Safety Information
CAUTION
Failure follow these requirements for cable routing conditions may expose the user to electrical shock and
may expose the unit to damage that can cause errors.
WARNING!
The Ethernet ports of the equipment and its sub-assemblies are suitable only for intra-building connections
(within the same building) or for connections to unexposed wiring or cabling. (See the conditions listed above.) The
Ethernet ports of this equipment or its sub-assemblies must not be metallically connected to interfaces that connect
to the outside plant (OSP) or its wiring. Ethernet interfaces are designed for use only as intra-building interfaces
(described as Type 2 or Type 4 ports in GR-1089-CORE, Issue 6) and require isolation from the exposed OSP
wiring. The addition of Primary Protectors is not sufficient protection to connect these interfaces metallically to
OSP wiring.
This warning does not apply to T1/E1 ports because T1/E1 ports have built-in isolation and surge protection that
allows them to be connected to OSP wiring.
Installing Power Supply Units and Connecting Power
For the ratings and power requirements of each power supply unit or router see
sheet for the equipment at http://www.extremenetworks.com.
WARNING!
Be sure to satisfy the requirements listed in this section when you install Extreme Networks power supplies
or connect power.
When you install any power supply:
Do not use excessive force when you insert a power supply into the bay.
●
Do not attempt to open the power supply enclosure for any reason; the power supply does not
●
contain user-serviceable parts. In the event of failure, return the defective power supply to Extreme
Networks for repair or replacement.
Do not put your hand into an open power supply bay when a power supply is not present. An
●
empty power supply bay requires a cover at all times.
Before you work on equipment that is connected to power lines, remove all jewelry, including
●
watches. Metal objects heat up when they are connected to power and ground and can cause serious
burns or weld the metal object to the terminals.
An electrical arc can occur when you connect or disconnect the power with power applied. This
●
could cause an explosion in hazardous area installations. Be sure that power is removed from the
device.
When you install or replace equipment, always make the ground connection first and disconnect the
●
ground connection last.
